Re: version compatibility

There is backward compatibility but forward compatibility is not
guaranteed. With CREATE TABLE there should be a way to edit the script
file to make it work with an older version. You can report it in the
Help forum.

It would be better to move to version 2.3.3 which will be
released shortly.
